I've had to format and reinstall windows on my desktop, but I'm missing a driver for Network Controller and can't seem to find the right one anywhere. Just wondering if anyone would know how the hell I can find what I need?

Network Controller is the only one in device manager to have that little yellow ! , stating that the drivers for this device are not installed. I believe i just need to install drivers for the PCI card, but I have NFI what ones to get or where to get them.

if desktop:
1) open your computer case, look on motherboard for model info and also look at the info printed on the top of the chips.
2) goto manufacturers website and download all drivers for the board, look for any network/communication/chipset devices (as fitz said it may not necessarily be the onboard NIC) - knowing what actual chips you have soldered to the m/b can be handy at this point (as suggested in #1) as some of the drivers may differ or support multiple versions of a device
3) install and be happy
if laptop:
1) goto manufacturers website and d/l all drivers and install - if they have a downloadable driver disk get that and let it do it all automagically

Turns out there wasn't a wireless element to whatever I had in there, it was previously all done through an external adapter. I originally bought it through a friend at a local netcafe and he forgot to include the driver disk for the adapter, which is all I needed -_-
